54101-G0807LF Equivalent & Substitute Parts

Part Overview

The 54101-G0807LF is a rectangular connector header manufactured by Amphenol ICC (FCI) under the BERGSTIK® series. This through-hole mounted connector features 7 positions with 0.100" (2.54mm) pitch spacing and is designed for board-to-board applications. The part is currently active in production with full inventory availability. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to supply constraints, design flexibility, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 54101-G0807LF is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Pitch: 7 positions at 0.100" (2.54mm) spacing
• Row Configuration: Single row layout
• Mounting & Termination: Through-hole solder termination
• Electrical Performance: 3A per contact current rating capability
• Environmental Compliance: RoHS compliance and MSL 1 rating

The substitute part TS-107-T-AA from Samtec Inc. meets all critical substitution criteria. Both parts share identical position count, pitch spacing, row configuration, mounting type, and termination method. Both are RoHS compliant with MSL 1 rating, ensuring compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 54101-G0807LF and TS-107-T-AA are active production parts with full RoHS compliance and MSL 1 rating. Selection between these parts should be based on:

54101-G0807LF (Amphenol ICC): Primary choice when gold-plated mating contacts are required for enhanced corrosion resistance and contact reliability in demanding environments. The BERGSTIK® series designation indicates established design heritage.

TS-107-T-AA (Samtec Inc.): Suitable alternative when tin-plated contacts are acceptable. The higher post contact finish thickness (200.0µin vs. 100.0µin) provides additional solder joint durability. Samtec packaging in tube format may offer logistics advantages in certain supply scenarios.

Both parts operate across the -65°C to 125°C temperature range and support 3A per contact current capacity, making them functionally equivalent for standard board-to-board header applications.

Frequently Asked Questions (FAQ)

Q: Can TS-107-T-AA be used as a direct replacement for 54101-G0807LF?

A: Yes, for applications where contact finish material is not a critical design parameter. The TS-107-T-AA provides equivalent electrical and mechanical performance with identical position count, pitch, row configuration, and mounting characteristics. The primary difference is the contact finish specification: 54101-G0807LF features gold-plated mating contacts while TS-107-T-AA uses tin plating.

Q: What are the key compatibility factors for these connectors?

A: Compatibility is ensured through matching specifications: 7-position single-row configuration, 0.100" (2.54mm) pitch spacing, through-hole solder termination, and male pin contact type. Both parts maintain identical mechanical envelope and mounting footprint.

Q: How do the packaging formats differ?

A: The 54101-G0807LF is supplied in bag packaging, while TS-107-T-AA is supplied in tube packaging. This difference affects handling and storage but does not impact electrical or mechanical performance.

Q: Are both parts compliant with current regulatory standards?

A: Yes. The 54101-G0807LF is RoHS Compliant, and TS-107-T-AA is ROHS3 Compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating and are REACH Affected. Both carry EAR99 ECCN classification.

Q: What is the significance of contact finish thickness differences?

A: The 54101-G0807LF specifies 30.0µin (0.76µm) gold plating on mating contacts and 100.0µin (2.54µm) tin on posts. The TS-107-T-AA specifies 200.0µin (5.08µm) tin finish on posts. Higher tin thickness on the TS-107-T-AA post provides increased solder joint robustness in high-cycle assembly environments.
