Key Parameters

Substitute Part Grouping Explanation

Substitution for the TE Connectivity 644898-2 is determined by the following critical parameters:

Direct Equivalent (Same Manufacturer): The 3-644898-2 is a direct equivalent within the TE Connectivity CST-100 series. Both parts share identical electrical and mechanical specifications: 2-position, 0.100" (2.54mm) pitch, through-hole right-angle mounting, shrouded 4-wall configuration, 250VAC voltage rating, and -55°C to 105°C operating temperature range. The primary difference is product status: 3-644898-2 is active, whereas 644898-2 is obsolete. Packaging differs (bulk versus standard), and RoHS compliance status is updated to current standards.

Cross-Manufacturer Alternative (Similar Functionality): The JST Sales America S2B-XH-A-1 provides functional substitution with notable parameter variations. While both connectors maintain 2-position configuration, shrouded 4-wall design, through-hole right-angle mounting, and UL94 V-0 flammability rating, the JST part operates at a slightly different pitch (0.098" / 2.50mm versus 0.100" / 2.54mm). Operating temperature range is reduced (-25°C to 85°C versus -55°C to 105°C), and contact material differs (brass versus copper alloy). The JST connector supports press-fit and solder termination, whereas the TE part supports solder only.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The 3-644898-2 is the primary substitute for the obsolete 644898-2. Both parts are manufactured by TE Connectivity within the CST-100 series and maintain identical electrical and mechanical specifications. The 3-644898-2 is active in production, ensuring long-term availability. This part is suitable for applications requiring no design modification and is recommended for designs currently using the 644898-2.

For Cross-Manufacturer Substitution: The JST S2B-XH-A-1 serves as a functional alternative when TE Connectivity parts are unavailable or when design flexibility permits component change. This substitution requires engineering evaluation due to parameter differences: reduced operating temperature range (-25°C to 85°C), different pitch tolerance (0.098" versus 0.100"), and alternative contact materials. The JST connector is suitable for applications operating within the reduced temperature range and where pitch tolerance variation is acceptable. Both parts maintain UL94 V-0 flammability rating and RoHS3 compliance.

Compliance Considerations: All three parts are RoHS compliant and carry EAR99 export classification. The 3-644898-2 and S2B-XH-A-1 are both active products with established supply chains, supporting long-term design continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3-644898-2 be used as a direct replacement for the 644898-2?

A: Yes. The 3-644898-2 is a direct equivalent with identical electrical and mechanical specifications. Both parts share the same pitch (0.100" / 2.54mm), 2-position configuration, through-hole right-angle mounting, shrouded 4-wall design, 250VAC voltage rating, and -55°C to 105°C operating temperature range. The primary advantage of the 3-644898-2 is active product status, ensuring ongoing availability.

Q: What are the key differences between the TE Connectivity 644898-2 and the JST S2B-XH-A-1?

A: The primary differences are pitch (0.100" versus 0.098"), operating temperature range (-55°C to 105°C versus -25°C to 85°C), contact material (copper alloy versus brass), contact finish on mating surface (gold versus tin), insulation material (polyester versus polyamide/nylon), and fastening mechanism (friction lock versus detent lock). Both maintain 2-position configuration, shrouded 4-wall design, and UL94 V-0 flammability rating.

Q: Is the JST S2B-XH-A-1 suitable for applications requiring -55°C operation?

A: No. The JST S2B-XH-A-1 operates from -25°C to 85°C, which does not meet the lower temperature requirement of -55°C. Applications requiring -55°C operation must use the TE Connectivity 644898-2 or 3-644898-2.

Q: Are there packaging differences between the 644898-2 and 3-644898-2?

A: Yes. The 644898-2 is supplied in standard packaging, while the 3-644898-2 is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: Can the JST S2B-XH-A-1 be used in applications with 0.100" (2.54mm) pitch requirements?

A: The JST S2B-XH-A-1 operates at 0.098" (2.50mm) pitch, which differs from the 0.100" (2.54mm) specification. While the difference is small, applications with strict pitch tolerance requirements should use TE Connectivity parts to maintain exact 0.100" (2.54mm) spacing.

Q: Are all three parts RoHS compliant?

A: Yes. The 644898-2, 3-644898-2, and S2B-XH-A-1 are all RoHS compliant. The 644898-2 and S2B-XH-A-1 carry ROHS3 compliance designation, while the 3-644898-2 carries RoHS compliance designation.

Q: What is the current rating for these connectors?

A: The TE Connectivity 644898-2 and 3-644898-2 have current ratings that vary by wire gauge. The JST S2B-XH-A-1 is rated for 3A.

Q: Do these connectors support press-fit termination?

A: The TE Connectivity 644898-2 and 3-644898-2 support solder termination only. The JST S2B-XH-A-1 supports both press-fit and solder termination, providing additional assembly flexibility.
