TE Connectivity 350830-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350830-2 is a 15-position header connector from the Universal MATE-N-LOK series, designed for board-to-cable/wire applications. This rectangular connector features a 0.250" (6.35mm) pitch with through-hole solder termination and gold-plated mating contacts. The part is currently active in production with 648 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, allowing for component interchangeability in applications where specific contact finish or compliance requirements differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 350830-2 are identified based on strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Number of positions: 15
• Number of rows: 3
• Pitch - mating: 0.250" (6.35mm)
• Row spacing - mating: 0.250" (6.35mm)
• Mounting type: Through hole
• Connector type: Header
• Contact type: Female socket
• Fastening type: Locking ramp
• Insulation material: Polyamide (PA), Nylon
• Insulation height: 0.550" (13.97mm)
• Contact shape: Circular
• Contact material: Phosphor bronze
• Contact length - post: 0.155" (3.94mm)

Electrical Compatibility Parameters:

• Termination: Solder
• Style: Board to cable/wire

The primary differentiators between the main part and substitutes are contact finish specifications (gold versus tin) and material flammability ratings (UL94 V-0 versus UL94 V-2), along with RoHS compliance status. These variations allow for substitution in applications where the specific contact finish or regulatory compliance requirements differ.

Parameter Comparison

Engineering Selection Recommendations

350830-2 (Primary Specification)

The 350830-2 features gold-plated mating contacts with tin-lead post finish and UL94 V-0 flammability rating. This part is RoHS non-compliant and carries REACH Affected status. Selection of this part is appropriate for applications requiring gold contact finish for enhanced corrosion resistance and superior electrical performance in low-signal applications.

350830-1 (Preferred Substitute)

The 350830-1 maintains identical mechanical and electrical parameters to the 350830-2, including the UL94 V-0 flammability rating. This part achieves RoHS compliance and carries the same base product number (350830), indicating design equivalence. The primary difference is the tin contact finish on both mating and post surfaces. This part is suitable for applications where RoHS compliance is required and gold contact finish is not a critical requirement.

350765-4 (Alternative Substitute)

The 350765-4 provides full mechanical and electrical compatibility with identical 15-position, 0.250" pitch configuration. This part achieves RoHS compliance with tin contact finish. The material flammability rating is UL94 V-2, which differs from the V-0 rating of the primary part. This part carries a different base product number (350765) and REACH status is vendor undefined. Selection of this part is appropriate for applications where UL94 V-2 flammability rating is acceptable and RoHS compliance is required.

Frequently Asked Questions (FAQ)

Q: Can 350830-1 be used as a direct replacement for 350830-2?

A: The 350830-1 maintains all critical mechanical and electrical parameters including connector type, position count, pitch, mounting method, and fastening mechanism. The primary differences are contact finish (tin versus gold) and RoHS compliance status. Substitution is valid where gold contact finish is not a functional requirement and RoHS compliance is acceptable or required.

Q: What is the difference between 350830-1 and 350765-4?

A: Both parts feature tin contact finish and RoHS compliance. The 350830-1 maintains UL94 V-0 flammability rating identical to the primary 350830-2 part, while 350765-4 has UL94 V-2 rating. The 350830-1 shares the same base product number (350830) as the primary part, indicating closer design lineage. Selection between these two depends on flammability rating requirements for the application.

Q: Why does 350830-2 have gold contacts while the substitutes have tin?

A: Contact finish selection is determined by application requirements. Gold plating provides superior corrosion resistance and is preferred for low-signal, low-current applications. Tin finish is suitable for general-purpose applications and is more cost-effective. Both finishes are compatible with the same connector body and mating interface.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical mechanical specifications: 15 positions, 3 rows, 0.250" pitch, through-hole mounting, locking ramp fastening, and identical insulation dimensions. They are mechanically interchangeable in the same PCB footprint and mating interface.

Q: What does RoHS compliance mean for these connectors?

A: RoHS compliance indicates the part does not contain restricted substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers above specified thresholds. The 350830-2 is RoHS non-compliant due to its tin-lead post finish. The 350830-1 and 350765-4 are RoHS compliant.

Q: Which part should be selected for new designs?

A: For new designs, the 350830-1 is the recommended selection. It maintains the UL94 V-0 flammability rating of the primary part while achieving RoHS compliance. This part provides the best balance of performance characteristics and regulatory compliance for current manufacturing standards.

Q: Can 350765-4 be used in applications requiring UL94 V-0 rating?

A: No. The 350765-4 carries UL94 V-2 flammability rating, which differs from the V-0 requirement. Applications with specific UL94 V-0 requirements must use either 350830-2 or 350830-1.

Q: What is the packaging difference between these parts?

A: The 350830-2 packaging is not specified in the available data. Both 350830-1 and 350765-4 are supplied in tray packaging. Packaging format may affect handling, storage, and assembly processes.
