Keystone Electronics 959 RJ45 Waterproof Modular Connector
Part Overview
The Keystone Electronics 959 is an RJ45 (8p8c) waterproof jack modular connector designed for panel mount and bulkhead applications. This connector features straight orientation with IDC termination and IP68 ingress protection rating, making it suitable for harsh environmental conditions requiring dust-tight and waterproof sealing.
The 959 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure availability for new production runs, repairs, and system upgrades where this connector type is specified.

Substitute Part Grouping Explanation
The Keystone Electronics 987 qualifies as a direct substitute for the 959 based on the following critical parameters:
Matching Parameters:
- Connector Type: Jack
- Contact Configuration: 8p8c (RJ45, Ethernet)
- Port and Row Configuration: 1 port, 1 row
- Mounting Type: Panel Mount, Bulkhead
- Orientation: Straight
- Termination Method: IDC
- Ingress Protection: IP68 - Dust Tight, Waterproof
- Contact Material: Phosphor Bronze
- Contact Finish: Gold
- Housing Material: Thermoplastic
- RoHS Compliance: ROHS3 Compliant
- MSL Rating: 1 (Unlimited)
The 987 maintains functional and mechanical compatibility with the 959 across all critical electrical and environmental parameters. The primary distinction is product status: the 987 is active and currently in production, whereas the 959 is obsolete.

Engineering Selection Recommendations
The Keystone Electronics 987 is the direct substitute for the obsolete 959 model. Both components maintain identical electrical, mechanical, and environmental specifications across all critical parameters. The 987 is currently in active production with confirmed inventory availability (1555 units in stock), ensuring supply chain continuity.
Both parts comply with ROHS3 regulations and carry REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either component.
For applications requiring the 959 specification, the 987 provides full functional equivalence without design modification or re-qualification.
Frequently Asked Questions (FAQ)
Q: Can the Keystone 987 be used as a direct replacement for the 959 in existing designs?
A: Yes. The 987 maintains identical contact configuration (8p8c RJ45), mounting type (panel mount/bulkhead), termination method (IDC), and ingress protection rating (IP68). No design changes are required.
Q: Are there differences in shielding between the 959 and 987?
A: The 959 shielding specification is not provided in the component data. The 987 is specified as unshielded. For applications where shielding is critical, this parameter must be evaluated against your system requirements.
Q: What is the difference in packaging between these parts?
A: The 959 packaging specification is not provided. The 987 is supplied in bulk packaging. Confirm packaging requirements for your procurement process.
Q: Are both parts compliant with current environmental and regulatory standards?
A: Yes. Both the 959 and 987 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated industries.
Q: What is the MSL rating, and does it affect storage or handling?
A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard component storage and handling procedures apply.
