Substitute Part Grouping Explanation

Substitute parts for the SFC-110-T2-L-D-TR are qualified based on strict electrical and mechanical parameter matching within the Tiger Eye™ SFC series. The substitution criteria are:

Identical connector type (Receptacle)
Identical number of positions (20)
Identical pitch specifications (0.050" mating pitch, 0.050" row spacing)
Identical number of rows (2)
Identical mounting type (Surface Mount)
Identical contact finish (Gold)
Identical electrical ratings (3.1A per contact, 350VAC)
Identical operating temperature range (-55°C ~ 125°C)
Identical insulation material (LCP)
Identical compliance status (ROHS3, MSL 1)

The identified substitutes differ only in optional features such as board guide presence or pick-and-place markings, which do not affect core electrical or mechanical compatibility.

SFC-110-T2-L-D-K-TR: Includes pick-and-place markings only. Suitable for automated assembly without board guide requirements.

All parts maintain ROHS3 compliance and MSL 1 rating. Inventory availability varies: SFC-110-T2-L-D-A-K-TR (2728 pcs), SFC-110-T2-L-D-K-TR (1177 pcs), and SFC-110-T2-L-D-TR (723 pcs).

Frequently Asked Questions (FAQ)

Q: Can SFC-110-T2-L-D-A-K-TR be used as a direct replacement for SFC-110-T2-L-D-TR?

A: Yes. Both parts share identical electrical ratings (3.1A per contact, 350VAC), mechanical dimensions (20 positions, 0.050" pitch), and compliance certifications (ROHS3, MSL 1). The board guide feature in the substitute does not affect electrical compatibility.

Q: What is the difference between SFC-110-T2-L-D-A-K-TR and SFC-110-T2-L-D-K-TR?

A: SFC-110-T2-L-D-A-K-TR includes both a board guide and pick-and-place markings, while SFC-110-T2-L-D-K-TR includes only pick-and-place markings. Both maintain identical electrical and mechanical specifications.

Q: Are these parts interchangeable in terms of mating with connector plugs?

A: Yes. All three receptacle variants share identical mating pitch (0.050"), row spacing (0.050"), and contact geometry, ensuring compatibility with the same plug connectors.

Q: Do the substitute parts have the same operating temperature range?

A: Yes. All parts operate across -55°C to 125°C, maintaining identical thermal performance specifications.

Q: What is the significance of the "K" designation in the part number?

A: The "K" designation indicates the presence of pick-and-place markings for automated assembly. The "A" prefix in SFC-110-T2-L-D-A-K-TR indicates the additional board guide feature.

Q: Are all three parts ROHS3 compliant?

A: Yes. All variants are ROHS3 compliant with MSL 1 rating, suitable for high-reliability applications.
