Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0878315021 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 50
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Shrouding: Shrouded - 4 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

All identified substitute parts meet these mandatory criteria. Variations in contact length, insulation height, fastening type, contact finish specifications, and insulation material are permissible within the scope of board-to-board connector interchangeability, provided the mating interface and electrical performance remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 10075025-G01-50ULF and 98414-G06-50LF: Both Amphenol ICC parts maintain full shrouded 4-wall configuration with identical pitch, position count, and row spacing. These parts are RoHS compliant with higher voltage rating (200V) than the original specification. The 98414-G06-50LF offers significantly higher inventory availability (2298 units) in bulk packaging. Both are suitable for direct substitution in applications where the elevated voltage rating does not create design conflicts.

Samtec LTMM-125-02-G-D and LTMM-125-02-L-D: These Flex Stack series connectors provide ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C). Both maintain the required shrouded 4-wall configuration and 2.00mm pitch. The LTMM-125-02-G-D features gold post finish, while LTMM-125-02-L-D uses tin post finish. These parts are suitable for applications requiring higher temperature performance. Inventory availability is adequate (1089 and 677 units respectively).

Samtec TMMH-125-01-S-D-ES: This cuttable header variant differs in shrouding configuration (unshrouded) and insulation height (0.079" versus 0.252" on the original). This part is suitable only for applications where unshrouded configuration is acceptable and where the reduced insulation height does not conflict with board layout or clearance requirements. ROHS3 compliance and UL94 V-0 rating are maintained. Bulk packaging with 850 units in stock.

All substitute parts maintain the mandatory electrical and mechanical parameters required for 2.00mm pitch, 50-position, board-to-board header connectivity. Selection should be based on specific application requirements regarding shrouding, temperature range, voltage rating, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 10075025-G01-50ULF be used as a direct replacement for Molex 0878315021?

A: Yes. Both parts share identical pitch (0.079" / 2.00mm), position count (50), row configuration (2 rows), shrouding (4-wall), and mounting type (through-hole solder). The Amphenol part features a higher voltage rating (200V versus 125V) and GXT™ gold plating on mating contacts, making it electrically compatible and suitable for direct substitution.

Q: What is the key difference between Amphenol ICC 98414-G06-50LF and 10075025-G01-50ULF?

A: Both are Minitek® 2.00mm series headers with identical electrical and mechanical specifications. The primary differences are packaging format (bulk versus tube) and inventory availability. The 98414-G06-50LF is available in significantly higher quantity (2298 units) and bulk packaging, making it preferable for high-volume applications or when tube packaging is not required.

Q: Why does Samtec TMMH-125-01-S-D-ES have different shrouding than the original part?

A: The TMMH-125-01-S-D-ES is a cuttable header variant with unshrouded design and reduced insulation height (0.079" versus 0.252"). This configuration is suitable for applications where individual positions require separation or where space constraints necessitate lower profile headers. Compatibility depends on specific board layout and mating connector design.

Q: Are Samtec LTMM-125-02-G-D and LTMM-125-02-L-D interchangeable?

A: Both Samtec Flex Stack parts maintain identical pitch, position count, shrouding, and mounting specifications. The primary difference is contact finish: LTMM-125-02-G-D uses gold post finish while LTMM-125-02-L-D uses tin post finish. Both are interchangeable from a mechanical and electrical standpoint. Selection depends on soldering process compatibility and contact resistance requirements.

Q: Do all substitute parts meet RoHS compliance requirements?

A: All substitute parts listed are RoHS compliant. Molex 0878315021, Samtec LTMM-125-02-G-D, LTMM-125-02-L-D, and TMMH-125-01-S-D-ES are ROHS3 compliant. Amphenol ICC 10075025-G01-50ULF and 98414-G06-50LF are RoHS compliant. Compliance status is suitable for applications requiring RoHS certification.

Q: What packaging options are available among the substitute parts?

A: Tube packaging is available from Molex 0878315021, Amphenol ICC 10075025-G01-50ULF, and all Samtec parts except TMMH-125-01-S-D-ES. Bulk packaging is available from Amphenol ICC 98414-G06-50LF and Samtec TMMH-125-01-S-D-ES. Packaging selection should align with procurement and assembly process requirements.
