TSW-102-08-S-S Equivalent & Substitute Parts

Part Overview

The TSW-102-08-S-S is a vertical rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications with 2 positions at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts and tin-plated posts, suitable for applications requiring push-pull fastening and solder termination.

The TSW-102-08-S-S is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-102-08-S-S is determined by the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 2
Number of Rows: 1
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Contact Finish - Mating: Gold
Insulation Material: Polybutylene Terephthalate (PBT) or equivalent thermoplastic
Material Flammability Rating: UL94 V-0

The substitute parts identified meet these core electrical and mechanical requirements. Variations in contact length, contact finish thickness, and operating temperature ranges are within acceptable tolerances for equivalent functionality in standard board-to-board applications.

Engineering Selection Recommendations

77311-118-02LF (Amphenol ICC BERGSTIK® Series) is the primary direct substitute for TSW-102-08-S-S. This part maintains identical pitch, position count, and core electrical specifications while offering an extended operating temperature range (-65°C ~ 125°C). The part is currently active in production with substantial inventory availability (25,253 pcs). RoHS compliance and UL94 V-0 flammability rating are maintained. The thermoplastic insulation material is functionally equivalent to PBT for standard applications.

929647-02-02-I (3M 929 Series) is an alternative substitute meeting all core substitution criteria. This breakaway header variant provides identical pitch and position configuration with active product status. Operating temperature range is -40°C ~ 105°C, which is narrower than the original part. Current rating is specified at 2.5A per contact. This part is suitable for applications within its temperature specification.

929647-02-03-I is not a direct substitute due to 3-position configuration, which differs from the 2-position requirement of TSW-102-08-S-S.

Frequently Asked Questions (FAQ)

Q: Can 77311-118-02LF directly replace TSW-102-08-S-S in existing designs?

A: Yes. Both parts share identical pitch (0.100"), position count (2), contact type (male pin), mounting method (through hole), and termination (solder). The BERGSTIK® series maintains equivalent electrical and mechanical performance for board-to-board applications.

Q: What is the difference between the Samtec and Amphenol ICC parts?

A: The primary differences are contact length specifications and insulation material composition. Samtec uses phosphor bronze contacts with PBT insulation; Amphenol ICC uses phosphor bronze contacts with thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements. The Amphenol ICC part offers a wider operating temperature range (-65°C ~ 125°C vs. -55°C ~ 125°C).

Q: Is 929647-02-02-I suitable for high-temperature applications?

A: The 929647-02-02-I operates within -40°C ~ 105°C. Applications requiring operation below -40°C or above 105°C should use 77311-118-02LF, which supports -65°C ~ 125°C.

Q: Are all substitute parts RoHS compliant?

A: Yes. TSW-102-08-S-S (ROHS3 Compliant), 77311-118-02LF (RoHS Compliant), and 929647-02-02-I (RoHS Compliant) all meet RoHS requirements.

Q: What is the current rating difference between parts?

A: TSW-102-08-S-S does not specify a current rating. 77311-118-02LF is rated at 3A per contact. 929647-02-02-I is rated at 2.5A per contact. For applications requiring current specifications, 77311-118-02LF provides the highest rating.

Q: Can I use 929647-02-03-I as a substitute?

A: No. The 929647-02-03-I is a 3-position connector, while TSW-102-08-S-S is a 2-position connector. Position count is a critical substitution parameter and cannot be changed without design modification.
