TE Connectivity AMP Connectors 7-1437007-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 7-1437007-3 is a 36-position ribbon cable DIP header connector designed for through-hole mounting applications. This connector features IDC (Insulation Displacement Contact) termination and is configured with a vertical orientation. The part is currently active in production and maintains inventory availability of 945 pieces in new original condition.

Substitute parts are identified when equivalent functional performance can be achieved through alternative manufacturer part numbers that maintain compatibility across critical electrical and mechanical parameters. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or when compliance requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 7-1437007-3 is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Number of positions: 36 (fixed requirement)
• Cable pitch: 0.050" (1.27mm) (fixed requirement)
• Board-side pitch: 0.100" (2.54mm) (fixed requirement)

Mechanical Parameters:

• Number of rows: 2 (fixed requirement)
• Row spacing: 0.100" (2.54mm) (fixed requirement)
• Mounting type: Through hole (fixed requirement)
• Orientation: Vertical (fixed requirement)

Functional Parameters:

• Connector type: Ribbon cable, DIP header (fixed requirement)
• Cable termination: IDC (fixed requirement)
• Features: Feed through (fixed requirement)

Material Parameters:

• Contact finish thickness: 100.0µin (2.54µm) (fixed requirement)
• Color: Blue (fixed requirement)

Substitute parts must match all parameters listed above. Variations in contact finish material (tin versus tin-lead), wire gauge specifications, and RoHS compliance status do not prevent substitution when all other parameters align. The substitute part 1-1658525-2 meets all substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 7-1437007-3 and the substitute part 1-1658525-2 are active products from the same manufacturer and maintain identical mechanical and electrical specifications across all critical parameters. Selection between these parts is based on the following engineering considerations:

Primary Part (7-1437007-3):

• Tin-lead contact finish
• RoHS non-compliant status
• Higher current inventory availability (945 pieces)
• Wire gauge specification not provided

Substitute Part (1-1658525-2):

• Tin contact finish
• RoHS compliant status
• Adequate inventory availability (761 pieces)
• Wire gauge specification: 26-28 AWG, stranded or solid
• Series designation: 622

Selection of the substitute part 1-1658525-2 is appropriate when RoHS compliance is required for the end application or when the specified wire gauge range (26-28 AWG) aligns with system requirements. The primary part 7-1437007-3 remains suitable for applications where RoHS compliance is not mandated and tin-lead contact finish is acceptable.

Both parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, with identical moisture sensitivity level (MSL 1 - Unlimited) and contact finish thickness specifications.

Frequently Asked Questions (FAQ)

Q: Can the substitute part 1-1658525-2 be used in place of 7-1437007-3 without PCB redesign?

A: Yes. Both parts maintain identical mechanical pitch specifications (0.050" cable pitch, 0.100" board-side pitch), identical row spacing (0.100"), and identical through-hole mounting configuration. No PCB redesign is required for direct substitution.

Q: What is the difference between the tin-lead finish on 7-1437007-3 and the tin finish on 1-1658525-2?

A: Both finishes maintain the same thickness specification (100.0µin / 2.54µm). The primary difference is material composition. The tin finish on 1-1658525-2 supports RoHS compliance, while the tin-lead finish on 7-1437007-3 does not. Contact finish material does not affect mechanical or electrical compatibility for this connector type.

Q: Does the wire gauge specification on 1-1658525-2 (26-28 AWG) restrict its use?

A: The wire gauge specification on 1-1658525-2 indicates the supported cable conductor range. This specification does not prevent substitution; it defines the compatible ribbon cable types. Verify that your ribbon cable conductor gauge falls within the 26-28 AWG range for optimal performance.

Q: Are both parts suitable for feed-through applications?

A: Yes. Both the 7-1437007-3 and 1-1658525-2 include the feed-through feature, enabling signal pass-through capability in daisy-chain or multi-connector configurations.

Q: What is the significance of the Series 622 designation on 1-1658525-2?

A: The Series 622 designation identifies the product line within TE Connectivity's connector portfolio. This designation does not affect substitution compatibility; it is a manufacturer classification parameter.

Q: Are there any moisture sensitivity concerns with either part?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special moisture control requirements.

Q: Can these connectors be used in high-temperature applications?

A: Temperature specifications are not provided in the available parameters. Consult the manufacturer's detailed technical documentation for thermal performance data.

Q: What is the difference in inventory between the two parts?

A: The primary part 7-1437007-3 has 945 pieces in stock, while the substitute 1-1658525-2 has 761 pieces available. Both quantities represent adequate inventory for production applications.
