Engineering Selection Recommendations

All substitute parts listed maintain active product status and comply with RoHS requirements. Selection among substitutes is determined by specific application requirements:

5-146256-9 (TE Connectivity): Maintains copper alloy contact material consistent with the original part. Suitable for applications requiring operating temperatures up to 105°C. Gold contact finish provides enhanced corrosion resistance.

67997-218HLF (Amphenol ICC BERGSTIK® II): Phosphor bronze contact material with extended operating temperature range to 130°C. Gold or GXT™ finish options available. Increased insulation height to 0.100" (2.54mm).

77313-101-18LF (Amphenol ICC BERGSTIK®): Phosphor bronze contacts with 130°C operating temperature capability. Shorter post length (0.095") results in reduced overall contact length (0.425"). Gold or GXT™ finish available.

77313-118-18LF (Amphenol ICC BERGSTIK®): Phosphor bronze contacts with 130°C operating temperature capability. Post length (0.120") and overall contact length (0.450") provide dimensional consistency with other substitutes. REACH Status: REACH Affected.

PBC09DAAN (Sullins): Polybutylene Terephthalate (PBT) insulation with phosphor bronze contacts and gold finish. Operating temperature range -65°C to 125°C. MSL: Not Applicable.

PBC09DABN (Sullins): Extended post length (0.230") and overall contact length (0.560") for applications requiring deeper board penetration. PBT insulation, phosphor bronze contacts, gold finish. Operating temperature -65°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702871007 be directly replaced with any of these substitute parts?

A: Direct replacement is possible when the application accommodates variations in contact length, contact finish, and insulation material. The core mechanical interface (pitch, position count, row spacing, mounting type) remains identical across all parts in this group.

Q: What is the significance of contact length differences?

A: Contact length variations affect board penetration depth and mating force characteristics. The original Molex part features longer mating contact length (0.240") compared to most substitutes (0.230"). Applications with specific PCB thickness or connector depth requirements must account for these differences.

Q: How do contact finish options affect performance?

A: Tin finish provides cost efficiency and adequate corrosion resistance for general applications. Gold finish (10µin to 30µin thickness) offers superior corrosion resistance and lower contact resistance, beneficial for high-reliability or harsh environment applications. GXT™ finish variants provide enhanced durability.

Q: Are there temperature rating differences that affect substitution?

A: The original Molex part does not specify an operating temperature range. Substitute parts specify ranges from -65°C to 105°C (TE Connectivity) or -65°C to 130°C (Amphenol, Sullins). Applications requiring operation beyond 105°C should select Amphenol or Sullins alternatives.

Q: What is the difference between Copper Alloy and Phosphor Bronze contacts?

A: Copper Alloy (original Molex part) and Phosphor Bronze (most substitutes) both provide adequate electrical conductivity. Phosphor Bronze offers improved spring characteristics and wear resistance, beneficial for high-cycle mating applications.

Q: Does insulation material affect substitution compatibility?

A: Insulation material variations (LCP Glass Filled vs. PBT vs. Thermoplastic) do not affect electrical or mechanical interface compatibility. Material selection impacts thermal performance, dimensional stability, and cost. All materials specified maintain UL94 V-0 flammability rating.

Q: What does MSL (Moisture Sensitivity Level) indicate?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions. Sullins parts specify MSL: Not Applicable, indicating equivalent or superior moisture tolerance.

Q: Are all substitute parts RoHS compliant?

A: All parts listed are RoHS compliant. The original Molex part is ROHS3 Compliant. TE Connectivity and Amphenol parts are RoHS Compliant. Sullins parts are ROHS3 Compliant. REACH Status varies; 77313-118-18LF is REACH Affected while others are REACH Unaffected.

Q: Which substitute offers the highest inventory availability?

A: TE Connectivity 5-146256-9 provides the highest inventory with 2809 units in stock, compared to 852 units for the original Molex part.
