Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0761557308 is determined by the following critical parameters that must match or be compatible:

• Connector Type & Style: Header, Male Pins with Impact, Guide Left configuration
• Position Count: 72 positions
• Physical Layout: 12 rows × 6 columns
• Mounting Method: Through Hole with Press-Fit termination
• Contact Properties: Gold finish at 30.0µin thickness
• Environmental Ratings: UL94 V-0 flammability, operating range -55°C to 85°C, 30V voltage rating
• Compliance: ROHS3 compliant, REACH unaffected

The TE Connectivity AMP Connectors part 2149979-3 qualifies as a direct substitute based on matching connector type, style, position count, column configuration, mounting method, termination type, contact finish specifications, color, environmental operating range, flammability rating, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 2149979-3 is a qualified equivalent substitute for the Molex 0761557308. Both parts maintain identical compliance certifications including ROHS3 compliance and REACH unaffected status. Both are rated for the same environmental operating temperature range of -55°C to 85°C and carry UL94 V-0 flammability certification. The electrical and mechanical specifications are fully aligned across all critical parameters including connector configuration, position count, mounting method, and contact finish specifications.

Selection between these parts may be based on packaging format (Molex supplied in Tray; TE Connectivity supplied in Bulk), current inventory levels, or supply chain logistics. Both parts are active in production status and suitable for direct substitution in backplane connector applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2149979-3 be used as a direct replacement for the Molex 0761557308?

A: Yes. Both parts share identical connector type, style, position count, mounting method, termination type, contact finish specifications, and environmental ratings. They are mechanically and electrically interchangeable.

Q: What are the key parameters that determine substitution compatibility?

A: The critical parameters are: 72-position count, Impact style with Guide Left configuration, 12 rows × 6 columns layout, through-hole mounting with press-fit termination, gold contact finish at 30.0µin thickness, -55°C to 85°C operating range, UL94 V-0 flammability rating, and 30V voltage rating.

Q: Are there differences in packaging between these parts?

A: Yes. The Molex 0761557308 is supplied in Tray packaging, while the TE Connectivity 2149979-3 is supplied in Bulk packaging. This may affect handling, storage, and ordering quantities but does not impact functional compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with matching HTSUS code 8536.69.4040.

Q: What is the pitch specification for these connectors?

A: The Molex 0761557308 specifies a pitch of 0.053" (1.35mm). The TE Connectivity 2149979-3 does not provide explicit pitch documentation in available specifications but maintains the same 6-column configuration and connector style, indicating compatible pitch geometry.
