TE Connectivity 2-5499345-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-5499345-3 is a rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This 16-position connector operates at 0.100" (2.54mm) pitch with shrouded 4-wall construction and latch lock/eject hook fastening. The part is Active status and widely used in industrial and commercial electronic assemblies requiring reliable interconnection with keying slot protection and mounting flange support.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility permits selection from multiple qualified manufacturers meeting identical or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish compatibility:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (16)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (1 - Unlimited)

All substitute parts listed meet these critical parameters. Variations in contact length, insulation height, fastening hook length, contact material composition, and insulation material do not prevent functional substitution when the above core parameters align. Differences in operating temperature range, current rating, and contact finish specifications are noted but do not preclude substitution when application requirements fall within the substitute part's rated envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status products with full RoHS compliance and MSL 1 rating, ensuring long-term availability and environmental regulatory alignment with the primary TE Connectivity 2-5499345-3 part.

HARTING 09185166903 operates across an extended temperature range (-55°C ~ 125°C) compared to the primary part, providing thermal margin for applications requiring higher temperature performance. This part is packaged in Tray format and features long fastening hooks with ROHS3 compliance and REACH Unaffected status.

Amphenol ICC 71922-116LF (Quickie™ series) offers gold GXT™ mating contact finish with phosphor bronze contact material and glass-filled thermoplastic insulation. This part is supplied in Tube packaging and carries REACH Affected status, requiring compliance verification for specific end-use applications.

3M N3408-5202RB provides 1.75A current rating per contact, exceeding the primary part's 1A specification. This part features short fastening hooks, bulk packaging, and operates across -55°C ~ 105°C temperature range with PCT/Polyester glass-filled insulation.

3M N3408-5302RB matches the N3408-5202RB electrical specifications with identical 1.75A current rating and -55°C ~ 105°C operating range. This variant features long fastening hooks and Tray packaging, offering the same contact material and insulation composition.

3M N3408-5303RB provides extended contact post length (0.155" / 3.94mm) compared to other variants, accommodating applications requiring deeper board penetration or thicker PCB assemblies. This part maintains 1.75A current rating and -55°C ~ 105°C operating temperature with bulk packaging.

All substitute parts maintain identical 16-position, 2-row, 0.100" pitch configuration with shrouded 4-wall construction, keying slot, and mounting flange features required for direct mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09185166903 replace the TE Connectivity 2-5499345-3 in all applications?

A: The HARTING 09185166903 meets all critical mechanical and electrical parameters. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal capability. Verify that application requirements do not exceed the primary part's 250VAC voltage rating, as the HARTING part does not specify voltage rating in available documentation.

Q: What is the difference between the 3M N3408-5202RB, N3408-5302RB, and N3408-5303RB variants?

A: The primary differences are fastening hook length and contact post length. N3408-5202RB features short hooks with 0.112" post length. N3408-5302RB features long hooks with identical 0.112" post length. N3408-5303RB features long hooks with extended 0.155" post length for applications requiring deeper PCB penetration. All three share identical 1.75A current rating and -55°C ~ 105°C operating temperature.

Q: Does packaging format affect electrical or mechanical compatibility?

A: Packaging format (Bulk, Tray, Tube) does not affect connector electrical or mechanical performance. Packaging selection is determined by assembly process requirements, inventory management, and supply chain logistics. All substitute parts function identically regardless of packaging format.

Q: Are there current rating differences between the primary part and substitutes?

A: The TE Connectivity 2-5499345-3 is rated at 1A per contact. The 3M N3408 series parts (N3408-5202RB, N3408-5302RB, N3408-5303RB) are rated at 1.75A per contact, providing higher current capacity. The HARTING 09185166903 and Amphenol ICC 71922-116LF do not specify current rating. Applications operating below 1A per contact can use any substitute without current limitation concerns.

Q: What is the significance of contact material differences (Brass vs. Copper Alloy vs. Phosphor Bronze)?

A: All contact materials provide adequate electrical conductivity and mechanical durability for standard interconnection applications. Brass (primary part) and copper alloys (3M substitutes) offer similar performance characteristics. Phosphor bronze (Amphenol ICC) provides enhanced spring properties and wear resistance. Material selection does not prevent functional substitution when mating contact geometry and finish specifications align.

Q: Can the Amphenol ICC 71922-116LF be used in applications subject to REACH compliance requirements?

A: The Amphenol ICC 71922-116LF carries REACH Affected status, indicating that REACH compliance verification is required for specific end-use applications. Applications subject to REACH restrictions should confirm material composition and substance declarations with the manufacturer before selection.

Q: What does the difference in insulation height mean for PCB layout?

A: The primary TE part has 0.315" (8.00mm) insulation height. Substitute parts range from 0.335" to 0.340" (8.51mm to 8.64mm). These minor variations do not affect standard PCB layout or clearance calculations. Verify clearance only if the application has height-constrained mounting requirements below 0.340".

Q: Are all substitute parts suitable for high-temperature applications?

A: The HARTING 09185166903 operates to 125°C, exceeding the primary part's 105°C maximum. The 3M N3408 series and Amphenol ICC 71922-116LF operate to 105°C, matching the primary part. Applications requiring operation above 105°C should select the HARTING part. Applications operating below 105°C can use any substitute.
