Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-104-07-L-D-240-LL is determined by the following critical parameters:

Connector type: Header with male pins
Position count: 8 positions in 2-row configuration
Pitch specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting method: Through-hole solder termination
Current capacity: Minimum 3A per contact
Operating temperature range: Must support -55°C to 125°C minimum
Flammability compliance: UL94 V-0 rating required

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in contact length, insulation material, contact finish thickness, and series designation do not prevent functional substitution when the above parameters align.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with UL94 V-0 flammability requirements. Selection between the MTSW-104-07-L-D-240-LL and its substitutes should account for the following compliance considerations:

ROHS3 Compliant Options: The MTSW-104-07-L-D-240-LL (Samtec), 826632-4 (TE Connectivity), and M20-9760446 (Harwin) carry ROHS3 compliance. The Amphenol ICC parts carry either RoHS Compliant or RoHS Affected designations.

REACH Unaffected Options: The MTSW-104-07-L-D-240-LL (Samtec), 77313-122-08LF (Amphenol ICC), 826632-4 (TE Connectivity), and M20-9760446 (Harwin) are REACH Unaffected. The 77313-124-08LF, 77313-127-08LF, and 77313-822-08LF are REACH Affected.

Operating Temperature Range: The MTSW-104-07-L-D-240-LL operates from -55°C to 125°C. The Amphenol ICC BERGSTIK® parts and TE Connectivity 826632-4 support -65°C to 130°C or -65°C to 105°C respectively. The Harwin M20-9760446 operates from -40°C to 105°C, which does not cover the full lower temperature range of the original part.

Current Rating: The TE Connectivity 826632-4 provides 5A per contact, exceeding the 3A specification of the MTSW-104-07-L-D-240-LL and all other listed substitutes.

Frequently Asked Questions (FAQ)

Q: Can the 77313-822-08LF substitute for the MTSW-104-07-L-D-240-LL in all applications?

A: The 77313-822-08LF matches all critical electrical and mechanical parameters: 8 positions, 2 rows, 0.100" pitch, male pins, through-hole solder termination, 3A current rating, and UL94 V-0 flammability. However, it is REACH Affected while the MTSW-104-07-L-D-240-LL is REACH Unaffected. Regulatory requirements for your application determine suitability.

Q: What is the difference between the three Amphenol ICC BERGSTIK® options?

A: The 77313-122-08LF, 77313-124-08LF, and 77313-127-08LF differ in contact length specifications (mating and post lengths vary between 0.260" to 0.305" for mating contacts). All three maintain identical pitch, position count, current rating, and flammability compliance. Selection depends on PCB design requirements for contact engagement depth.

Q: Why does the M20-9760446 have a lower maximum operating temperature?

A: The Harwin M20-9760446 operates to 105°C maximum, compared to the MTSW-104-07-L-D-240-LL specification of 125°C. Applications requiring operation above 105°C must use the original part or select alternatives with higher temperature ratings such as the Amphenol ICC BERGSTIK® series.

Q: Is the TE Connectivity 826632-4 a direct substitute despite its 5A current rating?

A: The 826632-4 exceeds the 3A current requirement and maintains all other critical parameters. Higher current capacity does not prevent substitution. However, the insulation height is 0.110" (2.79mm) compared to 0.100" (2.54mm) for the MTSW-104-07-L-D-240-LL. PCB layout clearances must accommodate this dimensional difference.

Q: What packaging differences exist among these parts?

A: The MTSW-104-07-L-D-240-LL and most substitutes ship in Bulk packaging. The 77313-822-08LF is supplied in Bag packaging. Packaging does not affect electrical or mechanical function but may influence inventory handling and cost considerations.

Q: Are all substitutes suitable for high-reliability applications?

A: All listed parts carry UL94 V-0 flammability ratings and MSL 1 (Unlimited) moisture sensitivity levels. Compliance differences exist in RoHS and REACH designations. Applications with specific regulatory requirements must verify that selected substitutes meet those standards.
