Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTST-117-04-L-D-RA is determined by strict alignment of the following critical parameters:

• Connector type (Header), contact type (Male Pin), and number of positions (34 in 2 rows)
• Pitch and row spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder) and fastening type (Push-Pull)
• Contact dimensions (Mating length 0.250", Post length 0.130", Insulation height 0.365")
• Contact material (Phosphor Bronze) and finish specifications (Gold mating, Tin post)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS3 compliance

The identified substitutes TSS-117-04-L-D-RA and TST-117-04-L-D-RA maintain all critical electrical and mechanical parameters. Variations in insulation material composition and color do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. Selection between HTST-117-04-L-D-RA, TSS-117-04-L-D-RA, and TST-117-04-L-D-RA is based on insulation material requirements and environmental conditions.

HTST-117-04-L-D-RA employs Liquid Crystal Polymer (LCP) insulation with natural color and Not Applicable MSL rating, suitable for applications with minimal moisture sensitivity concerns.

TSS-117-04-L-D-RA uses Polybutylene Terephthalate (PBT) insulation with black color and MSL 1 (Unlimited) rating, appropriate for standard environmental exposure.

TST-117-04-L-D-RA incorporates glass-filled Polybutylene Terephthalate (PBT) insulation with black color and MSL 1 (Unlimited) rating, providing enhanced mechanical properties for applications requiring increased structural rigidity.

All parts share identical electrical characteristics, contact geometry, pitch specifications, and operating temperature range. Current inventory levels support immediate procurement across all three options.

Frequently Asked Questions (FAQ)

Q: Are TSS-117-04-L-D-RA and TST-117-04-L-D-RA fully interchangeable with HTST-117-04-L-D-RA?

A: Yes, within the specified electrical and mechanical parameters. All three parts maintain identical connector type, position count, pitch, mounting configuration, contact materials, and operating temperature range. Differences in insulation material composition do not affect functional interchangeability for standard board-to-cable/wire applications.

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

A: HTST-117-04-L-D-RA uses Liquid Crystal Polymer (LCP), while TSS-117-04-L-D-RA and TST-117-04-L-D-RA use Polybutylene Terephthalate (PBT). TST-117-04-L-D-RA includes glass reinforcement in the PBT formulation. These variations affect mechanical properties and environmental resistance but do not alter electrical performance or contact specifications.

Q: Do all parts support the same current rating?

A: HTST-117-04-L-D-RA and TST-117-04-L-D-RA are rated for 3.4A per contact. TSS-117-04-L-D-RA does not specify a current rating in the provided data. For applications requiring confirmed current capacity, HTST-117-04-L-D-RA or TST-117-04-L-D-RA are recommended.

Q: What does MSL rating indicate?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture during storage and handling. HTST-117-04-L-D-RA has Not Applicable MSL, while TSS-117-04-L-D-RA and TST-117-04-L-D-RA are rated MSL 1 (Unlimited), indicating minimal moisture sensitivity and flexible storage conditions.

Q: Are all parts RoHS3 compliant?

A: Yes, all three parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for lead-free and halogen-free applications.

Q: What is the difference between board-to-cable/wire and board-to-board style designations?

A: HTST-117-04-L-D-RA and TST-117-04-L-D-RA are specified for board-to-cable/wire applications. TSS-117-04-L-D-RA is designated for board-to-board or cable applications. All three maintain identical contact geometry and mounting specifications, supporting flexible application deployment.
