Substitute Part Grouping Explanation

Substitution of the 68691-208 is determined by strict alignment of the following electrical and mechanical parameters:

Connector type: Header with male pin contacts
Number of positions: 8 total positions
Number of rows: 2 rows
Pitch - mating: 0.100" (2.54mm)
Row spacing - mating: 0.100" (2.54mm)
Mounting type: Through hole
Termination: Solder
Fastening type: Push-pull
Contact shape: Square
Insulation height: 0.100" (2.54mm)

Engineering Selection Recommendations

The 68691-208 is obsolete and requires substitution for new designs and ongoing procurement. Selection among available substitutes depends on compliance requirements and product status:

For RoHS-compliant applications: The 929710-01-04-RK, 929710-06-04-RK, 929710-10-04-RK, 929710-11-04-RK, and 929715-01-04-EU are RoHS-compliant alternatives. All are active products from the 3M 929 series with identical core mating and mounting parameters.

For gold-plated contact finish: The 2308-6221-TG (3M 2300 series, active) and 929715-01-04-EU (3M 929 series, active) provide gold contact finish. The 929715-01-04-EU offers RoHS compliance with gold plating on both mating and post contacts.

For extended operating temperature range: The 2308-6221-TG supports -55°C to 105°C, compared to -40°C to 105°C for the 929 series alternatives.

For post length variations: The 929 series offers multiple post length options (0.110", 0.125", 0.175", 0.410", 0.710") to accommodate different PCB thicknesses and stacking requirements. Selection should match the original design's through-hole depth requirements.

For current rating: The 2308-6221-TG is rated for 3A, while the 929 series alternatives are rated for 2.5A. Applications requiring higher current capacity should specify the 2308-6221-TG.

Frequently Asked Questions (FAQ)

Q: Can the 929710 series directly replace the 68691-208?

A: Yes, the 929710 variants maintain identical mating pitch (0.100"), row spacing (0.100"), number of positions (8), number of rows (2), mounting type (through hole), termination (solder), and fastening type (push-pull). The primary differences are contact finish, post length, and insulation material. Selection depends on specific post length and compliance requirements.

Q: What is the difference between the various 929710 part numbers?

A: The 929710 series differs primarily in contact post length and contact finish. The numeric suffix indicates post length: -01-04 (0.110"), -03-04 (0.410"), -06-04 (0.710"), -10-04 (0.175"), -11-04 (0.125"). The -RK suffix indicates tin plating and RoHS compliance, while non-RK variants use tin-lead plating and are RoHS non-compliant.

Q: Is the 2308-6221-TG compatible with the same mating connectors as the 68691-208?

A: Yes. The 2308-6221-TG maintains the same 0.100" (2.54mm) pitch, 2-row configuration, and push-pull fastening. It is mechanically and electrically compatible with connectors designed for the 68691-208.

Q: What post length should I select for my application?

A: Post length selection depends on PCB thickness and stacking height requirements. The original 68691-208 has a 0.120" (3.05mm) post length. The 929710-11-04-RK (0.125") provides the closest match. For thicker PCBs or extended stacking, longer post options (929710-10-04-RK at 0.175" or 929710-06-04-RK at 0.710") are available.

Q: Are there RoHS-compliant alternatives?

A: Yes. The 929710-01-04-RK, 929710-06-04-RK, 929710-10-04-RK, 929710-11-04-RK, and 929715-01-04-EU are all RoHS-compliant. The 2308-6221-TG is RoHS non-compliant.

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

A: Tin-lead finishes (non-RK variants) are RoHS non-compliant but offer established solderability characteristics. Tin finishes (RK variants) are RoHS-compliant with thicker plating (200.0µin vs. 100.0µin) to ensure equivalent contact reliability and solderability performance.

Q: Can I use the 929715-01-04-EU as a direct replacement?

A: Yes. The 929715-01-04-EU is mechanically and electrically compatible with the 68691-208. It provides gold plating on both mating and post contacts, RoHS compliance, and is an active product. Post length (0.110") is slightly shorter than the original (0.120"), which may require PCB design verification for through-hole depth compatibility.
