Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLM-104-02-F-D-TR is determined by strict alignment of the following parameters:

• 8-position receptacle configuration with 2-row layout
• 0.039" (1.00mm) mating pitch and row spacing
• Surface mount solder termination with push-pull fastening
• Gold-plated mating contacts
• Phosphor bronze contact material
• Liquid crystal polymer insulation
• UL94 V-0 flammability rating
• ROHS3 compliance

The substitute part BC085-08-A-0390-L-C meets these core electrical and mechanical requirements, enabling functional equivalence in board-to-board connector applications requiring 1.00mm pitch 8-position receptacle configurations.

Parameter Comparison

Engineering Selection Recommendations

Both the CLM-104-02-F-D-TR and BC085-08-A-0390-L-C are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts depends on application-specific requirements:

The CLM-104-02-F-D-TR supports higher current capacity at 2.8A per contact and operates across a wider temperature range (-55°C to 125°C), making it suitable for demanding thermal and power delivery environments.

The BC085-08-A-0390-L-C provides rated voltage specification (250VAC/DC) and includes pick-and-place features for automated assembly. Its operating range (-40°C to 105°C) covers standard industrial and commercial applications. Current capacity is rated at 1A per contact.

Both parts share identical mating pitch, row configuration, contact material composition, insulation material, and flammability rating, establishing mechanical and electrical compatibility for board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can BC085-08-A-0390-L-C replace CLM-104-02-F-D-TR in all applications?

A: Substitution is valid when application requirements do not exceed BC085-08-A-0390-L-C specifications. The substitute part supports 1A per contact current (versus 2.8A) and operates to 105°C maximum (versus 125°C). Verify application current and temperature requirements before substitution.

Q: What are the key mechanical compatibility factors?

A: Both connectors share 0.039" (1.00mm) mating pitch, 2-row configuration with identical row spacing, surface mount solder termination, and push-pull fastening. Insulation height differs by 0.005" (0.12mm), which may affect PCB layout clearances in space-constrained designs.

Q: Are there differences in contact finish specifications?

A: CLM-104-02-F-D-TR specifies 3.00µin (0.076µm) gold plating thickness on mating contacts. BC085-08-A-0390-L-C specifies flash gold plating. Both provide gold-plated mating surfaces; thickness variation may affect long-term contact resistance in high-cycle mating applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification. Compliance profiles are equivalent for regulatory and environmental requirements.

Q: What is the significance of "Bottom or Top Entry" for the BC085 connector?

A: This designation indicates the mating connector can engage from either the bottom or top surface of the receptacle. This provides design flexibility in board layout and mating connector orientation compared to standard single-entry designs.
