Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 1-917658-3 and the equivalent part 1-917658-5 is based on the following critical parameters that define functional interchangeability:

Electrical Compatibility Parameters:

• Identical pitch spacing (0.200" / 5.08mm)
• Identical row spacing (0.300" / 7.62mm)
• Identical voltage rating (600V)
• Identical operating temperature range (-55°C ~ 105°C)

Mechanical Compatibility Parameters:

• Identical number of positions (12)
• Identical number of rows (2)
• Identical mounting type (Through Hole)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical fastening type (Detent Lock)
• Identical insulation height (0.850" / 21.59mm)
• Identical mated stacking heights (31.00mm ~ 32.50mm)

Material and Compliance Parameters:

• Identical insulation material (Thermoplastic, Polyester, Glass Filled)
• Identical flammability rating (UL94 V-0)
• Both RoHS compliant
• Identical moisture sensitivity level (MSL 1 - Unlimited)

Allowable Variations:

• Contact finish on mating surface (Gold vs. Tin)
• Contact finish thickness on mating surface (30.0µin vs. 78.7µin)
• Packaging format (Bulk vs. Tube)
• RoHS certification version (RoHS vs. ROHS3)

These variations do not affect the connector's ability to mate, align, or function within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 1-917658-3 and 1-917658-5 are active products from TE Connectivity's Dynamic D-3200 series and maintain full functional equivalence for board-to-board and cable connector applications. Selection between these parts is determined by packaging requirements and contact finish specifications rather than electrical or mechanical performance.

1-917658-3 (Gold Mating Finish):

• Bulk packaging format
• Gold contact finish on mating surface (30.0µin thickness)
• RoHS compliant
• Suitable for applications requiring enhanced corrosion resistance or where gold plating is specified

1-917658-5 (Tin Mating Finish):

• Tube packaging format
• Tin contact finish on mating surface (78.7µin thickness)
• ROHS3 compliant
• Higher inventory availability (7395 pcs vs. 861 pcs)
• Suitable for general purpose and industrial applications where tin finish meets performance requirements

Both parts satisfy UL94 V-0 flammability requirements, operate across the full -55°C to 105°C temperature range, and maintain 600V voltage rating specifications. The choice between these equivalents depends on procurement packaging preferences, contact finish requirements for the mating interface, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 1-917658-5 be used as a direct replacement for 1-917658-3 in existing circuit board designs?

A: Yes. Both connectors maintain identical pitch spacing (5.08mm), row spacing (7.62mm), number of positions (12), mounting type (through hole), and shrouding configuration. The mating interface dimensions and mechanical alignment are identical, allowing direct substitution without circuit board redesign.

Q: What is the difference between the gold and tin contact finishes?

A: The 1-917658-3 features a gold mating finish (30.0µin thickness) while the 1-917658-5 features a tin mating finish (78.7µin thickness). Gold provides enhanced corrosion resistance and is typically specified for applications requiring extended shelf life or harsh environmental exposure. Tin finish is suitable for general purpose and industrial applications with standard environmental conditions.

Q: Are there any electrical performance differences between these two parts?

A: No. Both connectors share identical voltage rating (600V), operating temperature range (-55°C to 105°C), and contact material (copper alloy). Electrical performance is equivalent across all specified parameters.

Q: What is the significance of the packaging difference (Bulk vs. Tube)?

A: Packaging format affects handling, storage, and procurement logistics but does not impact connector performance. Bulk packaging is suitable for high-volume manufacturing environments, while tube packaging provides organized component storage and is common for standard inventory management.

Q: Are both parts RoHS compliant?

A: Yes. The 1-917658-3 is RoHS compliant, and the 1-917658-5 is ROHS3 compliant. Both meet RoHS requirements for restricted substance elimination. ROHS3 represents the current RoHS certification standard.

Q: Can these connectors be used interchangeably with other TE Connectivity connector series?

A: No. These connectors are specific to the Dynamic D-3200 series. Mating with connectors from other series requires verification of pitch spacing, row spacing, number of positions, and shrouding configuration. Only connectors within the Dynamic D-3200 series with matching electrical and mechanical parameters are interchangeable.

Q: What is the moisture sensitivity level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Are there any temperature-related limitations for these connectors?

A: Both connectors operate across the full -55°C to 105°C temperature range. This range covers standard industrial and general purpose applications. No derating is required within this specified operating window.
