Parameter Comparison

Engineering Selection Recommendations

The 68021-136HLF serves as the direct active equivalent for the obsolete 78299-136H. Selection of the substitute part is based on the following engineering factors:

Product Status: The 68021-136HLF is classified as Active, ensuring ongoing availability and manufacturing support, whereas the 78299-136H is obsolete and subject to discontinuation.

Regulatory Compliance: The 68021-136HLF is RoHS Compliant and REACH Affected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions. The original 78299-136H is RoHS non-compliant and REACH Unaffected, which may present compliance challenges for new designs or applications subject to RoHS directives.

Electrical and Mechanical Specifications: Both parts maintain identical mating pitch (0.100" / 2.54mm), position count (36), row configuration (2 rows), contact geometry (square male pins), and contact material (phosphor bronze with gold finish). These parameters ensure mechanical and electrical interchangeability at the connector interface level.

Termination Consideration: The 68021-136HLF provides solder termination, whereas the 78299-136H offers both press-fit and solder options. For applications currently using press-fit termination, design modification to accommodate solder-only termination may be required.

Packaging: The 68021-136HLF is supplied in bag packaging, differing from the original part's packaging specification.

Frequently Asked Questions (FAQ)

Q: Are the 78299-136H and 68021-136HLF mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100" / 2.54mm), position count (36), row spacing (0.100" / 2.54mm), contact geometry (square male pins), and mounting configuration (through-hole, right-angle). The physical footprint and mating interface are equivalent.

Q: What is the primary reason for substitution?

A: The 78299-136H is classified as obsolete, making it subject to discontinuation and limited availability. The 68021-136HLF is an active product from the same manufacturer and series, ensuring continued supply and manufacturing support.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 68021-136HLF is RoHS Compliant, whereas the original 78299-136H is RoHS non-compliant. This makes the substitute suitable for applications and markets requiring RoHS compliance.

Q: Are there differences in termination methods?

A: The 78299-136H supports both press-fit and solder termination. The 68021-136HLF supports solder termination only. Applications currently using press-fit termination will require design modification to use solder attachment.

Q: What is the operating temperature range for the substitute part?

A: The 68021-136HLF is rated for -65°C to 125°C operation. The original 78299-136H does not specify an operating temperature range in the provided data.

Q: Are there electrical rating differences?

A: The 68021-136HLF specifies 3A per contact and 110V voltage rating. The original 78299-136H does not provide electrical ratings in the available data.

Q: What packaging is supplied with the substitute part?

A: The 68021-136HLF is supplied in bag packaging. Confirm packaging requirements for your application, as this may differ from the original part's packaging specification.

Q: Is the substitute part from the same manufacturer?

A: Yes. Both the 78299-136H and 68021-136HLF are manufactured by Amphenol ICC (FCI) and belong to the BERGSTIK® II connector series.
