Frequently Asked Questions (FAQ)

Q: What makes 173977-8 a suitable substitute for DF3F-8S-2R26(05)?

A: Both connectors share the same 8-position configuration, rectangular connector category, and support discrete wire termination. The substitute is an active product with documented specifications and current manufacturing support.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: Mechanical compatibility depends on the specific mounting and mating interface requirements of the original application. The substitute provides free-hanging in-line mounting. Physical verification against the original installation environment is necessary.

Q: What is the significance of the MSL rating difference?

A: The original part lists MSL as Not Applicable, while the substitute carries MSL 1 (Unlimited). This indicates the substitute has no moisture sensitivity restrictions and can be stored and handled without special environmental controls.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The substitute is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the pitch specification of the substitute?

A: The substitute features a pitch of 0.079" (2.00mm), which defines the center-to-center spacing between adjacent contact positions.
