HTSW-107-25-G-D Equivalent & Substitute Parts

Part Overview

The HTSW-107-25-G-D is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This vertical connector features 14 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnection. The part is ROHS3 compliant and maintains an operating temperature range of -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific material or color requirements necessitate component selection from equivalent alternatives.

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-107-25-G-D is determined by strict alignment of the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (14)
Number of rows (2)
Pitch spacing (0.100" / 2.54mm)
Row spacing (0.100" / 2.54mm)
Mounting type (Through Hole)
Termination method (Solder)
Contact material (Phosphor Bronze)
Contact finish on mating surface (Gold)
Operating temperature range (-55°C ~ 125°C)
Material flammability rating (UL94 V-0)
RoHS compliance (ROHS3)

The TSW-107-25-G-D meets all these criteria and qualifies as a direct substitute. Variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate) and insulation color do not affect electrical or mechanical compatibility when all other parameters remain constant.

Engineering Selection Recommendations

Both the HTSW-107-25-G-D and TSW-107-25-G-D are active products from Samtec Inc. with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and UL94 V-0 material flammability certification. Selection between these parts should be based on:

Inventory availability at the time of procurement
Insulation material preference (LCP vs. PBT)
Insulation color requirement (Natural vs. Black)
Moisture sensitivity level tolerance (Not Applicable vs. MSL 1)

The TSW-107-25-G-D offers unlimited moisture sensitivity rating, which may be advantageous in applications with extended storage or high-humidity environments prior to assembly.

Frequently Asked Questions (FAQ)

Q: Can TSW-107-25-G-D be used as a direct replacement for HTSW-107-25-G-D?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, mounting method, contact material, and operating temperature range. The difference in insulation material (LCP vs. PBT) does not affect electrical or mechanical compatibility.

Q: What is the significance of the insulation material difference?

A: Liquid Crystal Polymer (LCP) and Polybutylene Terephthalate (PBT) are both thermoplastic materials suitable for connector insulation. The selection between them depends on application-specific requirements such as thermal stability, chemical resistance, or dimensional stability under specific environmental conditions. Both materials meet UL94 V-0 flammability requirements.

Q: Does the insulation color difference affect functionality?

A: No. Insulation color (Natural vs. Black) is a visual identifier only and does not impact electrical performance or mechanical compatibility.

Q: What does MSL 1 (Unlimited) mean for the TSW-107-25-G-D?

A: Moisture Sensitivity Level 1 indicates the part can be stored indefinitely without moisture control measures prior to assembly. The HTSW-107-25-G-D lists MSL as Not Applicable, indicating no moisture sensitivity restrictions apply.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Identical pitch spacing (0.100"), row spacing (0.100"), contact length, and overall dimensions ensure both parts are compatible with the same PCB footprint and mating connector.

Q: What is the current inventory status for these parts?

A: HTSW-107-25-G-D: 949 pieces in stock. TSW-107-25-G-D: 901 pieces in stock. Inventory levels are subject to change and should be verified at time of purchase.
