Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 4-171826-3 (Primary Part)

The TE Connectivity 4-171826-3 maintains Active product status with RoHS Compliant certification and UL94 V-0 material flammability rating. This connector is suitable for applications requiring the specified 0.098" (2.50mm) pitch with 2A current capacity and 250VAC/350VDC voltage ratings. The tin-plated brass contacts and PA66 nylon insulation provide standard performance characteristics for general-purpose rectangular connector applications.

Molex 0022053031 (Substitute - Pitch Variant)

The Molex 0022053031 operates at 0.100" (2.54mm) pitch with ROHS3 Compliant status and UL94 V-0 flammability rating. This connector is suitable for applications where the slightly larger pitch tolerance is acceptable. The tin-plated contact finish matches the primary part specification. Inventory availability is significantly higher (22,487 units) compared to the primary part.

Molex 0022122034 (Substitute - Pitch Variant with Gold Finish)

The Molex 0022122034 operates at 0.100" (2.54mm) pitch with ROHS3 Compliant status and UL94 V-0 flammability rating. This connector features gold-plated mating contacts, which provide enhanced corrosion resistance compared to tin plating. Inventory availability is the highest among all options (64,834 units). The gold finish is suitable for applications requiring improved contact reliability in corrosive environments.

Molex 1718571003 (Substitute - Pitch Variant with Flammability Consideration)

The Molex 1718571003 operates at 0.100" (2.54mm) pitch with ROHS3 Compliant status. This connector features UL94 V-2 material flammability rating, which is lower than the primary part's UL94 V-0 rating. The gold-plated mating contacts provide enhanced corrosion resistance. This option is suitable for applications where UL94 V-2 compliance is acceptable and the pitch tolerance is compatible with the design.

Compliance and Certification Summary:

All identified substitute parts maintain Active product status and ROHS3 Compliant certification. The primary part and Molex 0022053031 and 0022122034 share UL94 V-0 flammability rating. Molex 1718571003 carries UL94 V-2 rating, which represents a lower flammability classification. All parts are classified as EAR99 and share the same HTSUS code (8536.69.4040), indicating equivalent trade classification.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the TE Connectivity 4-171826-3 and the Molex substitute parts?

A: The primary difference is the mating pitch specification. The TE Connectivity 4-171826-3 operates at 0.098" (2.50mm) pitch, while all Molex substitutes operate at 0.100" (2.54mm) pitch. Both pitch specifications are standard in rectangular connector applications. The connector type, mounting configuration, shrouding, and termination method remain identical across all parts.

Q: Can I use a Molex 0.100" (2.54mm) pitch connector in place of the TE Connectivity 0.098" (2.50mm) pitch connector?

A: Pitch compatibility depends on the mating connector and printed circuit board layout. The 0.100" (2.54mm) pitch is a standard specification in the KK254 series. If the application design accommodates 0.100" (2.54mm) pitch spacing, the Molex substitutes are functionally compatible. If the design requires 0.098" (2.50mm) pitch, the Molex parts are not suitable.

Q: What is the difference between tin-plated and gold-plated contact finishes?

A: The TE Connectivity 4-171826-3 features tin-plated mating contacts with 31.5µin (0.80µm) thickness. Molex 0022053031 also features tin plating. Molex 0022122034 and 1718571003 feature gold-plated mating contacts with 20.0µin (0.51µm) and 15.0µin (0.38µm) thickness respectively. Gold plating provides enhanced corrosion resistance and is suitable for applications exposed to moisture or corrosive environments. Tin plating is suitable for standard general-purpose applications.

Q: Are all substitute parts RoHS Compliant?

A: Yes. The TE Connectivity 4-171826-3 is RoHS Compliant. All Molex substitute parts (0022053031, 0022122034, and 1718571003) are ROHS3 Compliant, which represents the current RoHS directive compliance standard. Both compliance levels are acceptable for applications requiring RoHS certification.

Q: What is the significance of the UL94 V-0 versus UL94 V-2 flammability rating?

A: UL94 V-0 represents a higher flammability classification than UL94 V-2. The TE Connectivity 4-171826-3, Molex 0022053031, and Molex 0022122034 all carry UL94 V-0 rating. Molex 1718571003 carries UL94 V-2 rating. Applications requiring UL94 V-0 certification must use parts with that specific rating. Applications with UL94 V-2 requirements can use any of the listed parts.

Q: What is the current rating for the Molex substitute parts?

A: The current rating is not specified in the provided data for Molex 0022053031, 0022122034, and 1718571003. The TE Connectivity 4-171826-3 specifies a 2A current rating. When selecting substitute parts, verify that the application current requirements do not exceed the connector's rated capacity.

Q: What is the voltage rating for the Molex substitute parts?

A: The voltage rating is not specified in the provided data for Molex 0022053031, 0022122034, and 1718571003. The TE Connectivity 4-171826-3 specifies 250VAC and 350VDC voltage ratings. When selecting substitute parts, verify that the application voltage requirements are compatible with the connector's rated capacity.

Q: Are all parts suitable for automotive applications?

A: The TE Connectivity 4-171826-3 is specified for general-purpose applications. The Molex substitute parts (0022053031, 0022122034, and 1718571003) are specified for automotive, general-purpose, medical, and telecommunications applications. If automotive qualification is required, the Molex parts provide documented suitability for that application category.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: All parts, including the TE Connectivity 4-171826-3 and all Molex substitutes, carry MSL 1 (Unlimited) rating. This indicates that the connectors have unlimited shelf life and do not require special moisture control during storage or handling.

Q: How do the contact length specifications compare across the parts?

A: The TE Connectivity 4-171826-3 specifies contact length - mating of 0.295" (7.49mm) and contact length - post of 0.142" (3.60mm). Molex 0022053031 specifies 0.264" (6.70mm) mating and 0.141" (3.58mm) post. Molex 0022122034 specifies 0.264" (6.70mm) mating and 0.141" (3.58mm) post. Molex 1718571003 specifies 0.265" (6.73mm) mating and 0.100" (2.54mm) post. These dimensional variations are within acceptable tolerances for rectangular connector applications but should be verified against specific board layout requirements.
