Substitute Part Grouping Explanation

Substitution eligibility for the MMS-104-02-F-DV-TR is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), position count (8), mating pitch (0.079"/2.00mm), row configuration (2 rows with 0.079" spacing), mounting method (surface mount), termination type (solder), fastening mechanism (push-pull), mating contact finish (gold), current capacity (3.9A per contact), operating temperature range (-55°C to 125°C), insulation material (LCP), and contact material (phosphor bronze). Parts meeting all these specifications are classified as direct substitutes within the MMS series. Variations in secondary features such as pick-and-place compatibility or post-contact finish do not affect core electrical and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both MMS-104-02-F-DV-TR and MMS-104-02-F-DV-K-TR are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and production requirements. The MMS-104-02-F-DV-K-TR includes pick-and-place feature designation, which may provide advantages in automated assembly environments. Both parts maintain ROHS3 compliance, EAR99 export classification, and MSL 1 moisture sensitivity rating. No electrical or mechanical performance differences exist between these substitutes.

Frequently Asked Questions (FAQ)

Q: Are MMS-104-02-F-DV-TR and MMS-104-02-F-DV-K-TR electrically interchangeable? A: Yes. Both parts share identical electrical specifications including 3.9A per contact current rating, gold mating contact finish, phosphor bronze contact material, and -55°C to 125°C operating temperature range.

Q: Are these connectors mechanically compatible in the same PCB footprint? A: Yes. Both parts have identical mechanical dimensions: 8 positions, 0.079" (2.00mm) mating pitch, 2-row configuration with 0.079" row spacing, 0.177" (4.50mm) insulation height, and surface mount solder termination.

Q: What is the difference between the -DV-TR and -DV-K-TR variants? A: The primary difference is the pick-and-place feature designation on the -DV-K-TR variant. This does not affect electrical or mechanical compatibility. Both use identical push-pull fastening and gold-plated contacts.

Q: Can I substitute MMS-104-02-F-DV-K-TR for MMS-104-02-F-DV-TR in existing designs? A: Yes. The parts are direct substitutes with no design modifications required. Verify PCB assembly process compatibility if pick-and-place automation is a consideration.

Q: Are both parts RoHS compliant? A: Yes. Both MMS-104-02-F-DV-TR and MMS-104-02-F-DV-K-TR are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the current handling capacity per contact? A: Both parts are rated for 3.9A per contact, suitable for standard signal and moderate power distribution applications.
