Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0870894616 is determined by the following critical parameters:

• Pitch and Position Count: 0.079" (2.00mm) pitch with 46 positions in 2 rows
• Row Spacing: 0.079" (2.00mm) row-to-row spacing
• Connector Type: Header configuration with male pins
• Mounting: Through-hole solder termination
• Fastening: Push-pull mechanism
• Contact Configuration: Square male pins, unshrouded
• Flammability: UL94 V-0 rated insulation material

The substitute parts listed below maintain these core electrical and mechanical parameters, ensuring functional compatibility in applications requiring 46-position 2.00mm pitch header connectors with through-hole solder mounting.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 4-5176264-6 is the primary recommended substitute. This part maintains identical mating contact length (0.157" / 4.00mm) and overall contact length (0.319" / 8.10mm) to the original Molex connector, ensuring direct mechanical compatibility. The TE Connectivity part is active in production status and ROHS3 compliant, addressing regulatory requirements for new designs. Operating temperature range of -40°C to 105°C covers standard industrial applications.

Samtec MTMM-123-03-G-D-150 and Samtec MTMM-123-04-S-D-150 provide alternative solutions with extended operating temperature ranges (-55°C to 125°C), suitable for applications requiring broader thermal performance. Both Samtec parts feature cuttable connector design and are ROHS3 compliant. Contact length variations (0.150" mating / 0.093" or 0.114" post) require PCB layout verification to ensure proper mating depth and solder joint formation. Samtec parts specify 3A current rating, providing defined electrical performance where the original part does not.

All substitute parts maintain the critical 2.00mm pitch, 46-position configuration, push-pull fastening, and UL94 V-0 flammability rating required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-5176264-6 be used as a direct replacement for the Molex 0870894616?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (46), row configuration (2 rows), contact length dimensions, and fastening mechanism. The TE Connectivity part is active in production and ROHS3 compliant, making it suitable for new designs and production continuity.

Q: What is the difference between the two Samtec options?

A: Both MTMM-123-03-G-D-150 and MTMM-123-04-S-D-150 maintain the same pitch, position count, and row spacing. The primary differences are contact post length (0.093" versus 0.114") and contact finish on the post (gold versus tin). Selection depends on PCB pad depth requirements and soldering process specifications.

Q: Are there dimensional differences that affect PCB layout?

A: Contact length variations exist between the original Molex part and Samtec alternatives. The Molex and TE Connectivity parts have identical overall contact length (0.319" / 8.10mm). Samtec parts measure 0.302" (7.67mm) or 0.323" (8.20mm). PCB hole depth and solder joint clearance must be verified during design transition.

Q: Do all substitute parts meet the same compliance standards?

A: All substitute parts are UL94 V-0 rated and ROHS3 compliant. The original Molex part is RoHS non-compliant. Samtec and TE Connectivity parts are suitable for applications requiring modern regulatory compliance. ECCN and HTSUS classifications are identical across all parts.

Q: What is the difference between "Breakaway" and "Cuttable" connector types?

A: Breakaway connectors feature pre-defined separation points for individual position removal. Cuttable connectors allow custom separation at any position along the header strip. Both types maintain the same electrical and mechanical interface when used as complete 46-position assemblies.

Q: Are operating temperature specifications critical for substitution?

A: Operating temperature range is specified for substitute parts (-40°C to 105°C for TE Connectivity; -55°C to 125°C for Samtec) but not provided for the original Molex part. Application requirements determine whether extended temperature range is necessary. Standard industrial applications typically operate within -40°C to 105°C range.
