HTSW-103-14-L-S-LL Equivalent & Substitute Parts

Part Overview

The HTSW-103-14-L-S-LL is a through-hole rectangular connector header manufactured by Samtec Inc. in the HTSW series. This 3-position, 0.100" (2.54mm) pitch connector is designed for board-to-board or cable applications with unshrouded, male pin contacts. The part is currently active in production with 717 units in stock. Substitute parts are necessary when primary inventory is unavailable, when alternative termination methods are required, or when specific contact finish specifications must be met for particular applications.

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-103-14-L-S-LL is determined by the following critical parameters:

Pitch - Mating: 0.100" (2.54mm) — all substitutes must match exactly
Number of Positions: 3 — all substitutes must have identical position count
Number of Rows: 1 — all substitutes must maintain single-row configuration
Contact Type: Male Pin — all substitutes must use male pin contacts
Mounting Type: Through Hole — all substitutes must support through-hole mounting
Connector Type: Header — all substitutes must be header-style connectors
Contact Shape: Square — all substitutes must use square contact geometry
Insulation Height: 0.100" (2.54mm) — all substitutes must match this dimension

All four substitute parts meet these core electrical and mechanical compatibility criteria. Variations in contact finish, termination method, contact material, and insulation material do not prevent functional substitution when these primary parameters align.

Engineering Selection Recommendations

All four substitute parts are active products with full RoHS compliance and MSL 1 rating, making them suitable for direct substitution based on compliance and availability criteria.

68024-103HLF (Amphenol ICC BERGSTIK® II): Highest inventory availability (1978 units). Suitable for applications requiring standard solder termination. Contact post length of 0.150" (3.81mm) is the longest among all options, which may affect PCB layout considerations. Gold or GXT™ contact finish provides corrosion resistance equivalent to the primary part.

78229-103HLF (Amphenol ICC BERGSTIK® II): Largest inventory stock (4641 units). Offers press-fit termination option in addition to solder, providing assembly flexibility. Contact post length of 0.120" (3.05mm) closely matches the primary part's 0.110" specification. Suitable for applications requiring either termination method.

929700-11-03-RK (3M Series 929): Moderate inventory (1035 units). Breakaway header design with tin contact finish. Operating temperature range of -40°C to 105°C is narrower than the primary part's -55°C to 125°C specification. Suitable for standard temperature applications. Copper alloy contact material with 200.0µin tin finish provides different corrosion characteristics than gold-plated options.

929705-01-03-EU (3M Series 929): Good inventory availability (3031 units). Breakaway header design with gold contact finish matching the primary part's specification. Contact post length of 0.110" (2.79mm) is identical to the primary part. Operating temperature range of -40°C to 105°C is narrower than the primary part. Copper alloy contact material with gold plating provides compatibility with the primary part's contact finish approach.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the HTSW-103-14-L-S-LL?

A: Yes, all four substitute parts are mechanically and electrically compatible for board-to-board or cable applications. They share identical pitch (0.100"), position count (3), row configuration (1), contact type (male pin), and mounting method (through hole). Differences in contact finish, termination method, and contact material do not prevent functional substitution when core parameters align.

Q: What is the difference between the Amphenol ICC and 3M options?

A: Amphenol ICC BERGSTIK® II parts (68024-103HLF and 78229-103HLF) offer phosphor bronze contacts with gold or GXT™ finish. The 78229-103HLF adds press-fit termination capability. 3M Series 929 parts (929700-11-03-RK and 929705-01-03-EU) feature copper alloy contacts; the 929700 uses tin finish while the 929705 uses gold finish. All are functionally compatible.

Q: Does contact post length affect compatibility?

A: Contact post length variations (0.110" to 0.150") do not prevent electrical or mechanical substitution. However, post length affects PCB hole depth requirements and solder joint geometry. The 68024-103HLF has the longest post (0.150"), while the HTSW-103-14-L-S-LL and 929705-01-03-EU share the shortest (0.110"). Verify PCB design accommodates the selected part's post length.

Q: Are there temperature rating differences I should consider?

A: The HTSW-103-14-L-S-LL operates from -55°C to 125°C. The 3M Series 929 parts (929700-11-03-RK and 929705-01-03-EU) operate from -40°C to 105°C, which is a narrower range. The Amphenol ICC parts do not specify operating temperature. For applications requiring the full -55°C to 125°C range, the HTSW-103-14-L-S-LL is the only specified option.

Q: What is the difference between kinked pin and standard solder termination?

A: The HTSW-103-14-L-S-LL uses kinked pin termination, which provides mechanical retention during PCB assembly. All substitute parts use standard solder termination without the kinked feature. This does not affect electrical performance but may impact assembly process compatibility. The 78229-103HLF offers both press-fit and solder options for assembly flexibility.

Q: Which substitute has the best inventory availability?

A: The 78229-103HLF (Amphenol ICC) has the highest inventory with 4641 units in stock, followed by 929705-01-03-EU (3M) with 3031 units. The 68024-103HLF has 1978 units, and 929700-11-03-RK has 1035 units.

Q: Are all parts RoHS compliant?

A: Yes, all parts including the primary HTSW-103-14-L-S-LL are RoHS compliant. The primary part is ROHS3 compliant, while all substitutes are RoHS compliant. All parts have MSL 1 (Unlimited) moisture sensitivity rating.
