Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-112-14-S-S is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pin contacts
• Position Count & Row Configuration: 12 positions in single-row arrangement
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical & Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1 rating

The substitute part 6-146277-2 (TE Connectivity AMP Connectors) meets these core substitution criteria. Both parts share identical position count, pitch, mounting method, and termination type. Both are active products with equivalent compliance certifications and unlimited moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-112-14-S-S and 6-146277-2 are active products with current manufacturing support and equivalent compliance certifications. Selection between these parts should be based on the following provided specifications:

TSW-112-14-S-S (Samtec Inc.) is specified for applications requiring the full operating temperature range of -55°C to 125°C and phosphor bronze contact material with PBT insulation.

6-146277-2 (TE Connectivity AMP Connectors) operates within -65°C to 105°C and features copper alloy contacts with liquid crystal polymer insulation. This part includes a 3A current rating specification and offers breakaway connector capability. The contact finish thickness on the post is specified at 100.0µin (2.54µm), compared to the main part specification.

Both parts maintain identical pitch, position count, mounting method, termination type, and flammability rating. Both are RoHS compliant with MSL 1 rating and unlimited moisture sensitivity. Selection should account for specific application temperature requirements and material compatibility needs.

Frequently Asked Questions (FAQ)

Q: Can 6-146277-2 be used as a direct replacement for TSW-112-14-S-S?

A: Both parts share identical mechanical and electrical interface specifications: 12 positions, 0.100" (2.54mm) pitch, through-hole solder termination, and push-pull fastening. However, they differ in contact material (phosphor bronze vs. copper alloy), insulation material (PBT vs. LCP), and operating temperature range. Application-specific requirements must be evaluated before substitution.

Q: What are the key differences in operating temperature?

A: TSW-112-14-S-S operates from -55°C to 125°C, while 6-146277-2 operates from -65°C to 105°C. Applications requiring temperatures above 105°C or below -65°C must use the TSW-112-14-S-S. Applications within the -55°C to 105°C range are compatible with both parts.

Q: Are both parts RoHS compliant?

A: Yes. TSW-112-14-S-S is ROHS3 Compliant, and 6-146277-2 is RoHS Compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the significance of the different insulation materials?

A: TSW-112-14-S-S uses polybutylene terephthalate (PBT), while 6-146277-2 uses liquid crystal polymer (LCP). Both materials are UL94 V-0 rated. Material selection may affect mechanical properties, chemical resistance, and thermal performance in specific application environments.

Q: Does 6-146277-2 offer any additional features?

A: 6-146277-2 is designated as a breakaway connector type and includes a specified current rating of 3A. The TSW-112-14-S-S does not specify a current rating in the provided data.

Q: Are the contact dimensions identical?

A: Contact dimensions are similar but not identical. Contact length mating is 0.320" (8.13mm) for TSW-112-14-S-S versus 0.318" (8.08mm) for 6-146277-2. Contact length post is 0.110" (2.79mm) versus 0.125" (3.18mm). Overall contact length is 0.530" (13.46mm) versus 0.533" (14.65mm). Insulation height differs at 0.100" (2.54mm) versus 0.090" (2.29mm).

Q: What is the MSL rating for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations for storage and handling.
